Definitions

  • the invention pertains generally to electrical connectors. More specifically, the invention relates to an electrical connector for electrical association with a printed circuit board.
  • the connector includes a unique receptacle containing a plurality of dual-in-line female contacts which perform both wipe and contact functions with respect to the male pin contacts of a plug member adapted to be mated with the receptacle.
  • the connector is further provided with separable contact points for establishing electrical communication with a printed circuit board by means of standard plated through holes or solder pads provided on the printed circuit board.
  • the invention possesses numerous benefits and advantages over known electrical connectors.
  • the invention utilizes a reliable gas tight separable contact principle between the receptacle and the printed circuit board which allows the number of through holes in the printed circuit board to be reduced, thereby affording component placement flexibility as well as user cost reductions.
  • the separable connector does not require hole masking for the connector pads on the printed circuit board and, therefore, diminishes assembly labor requirements and its associated costs. Because of its flexibility and simplicity in use and installation, the electrical connector of the instant invention realizes a reduction in tooling costs and in the costs of ongoing maintenance.
  • a practical example of the flexibility possessed by the invention resides in its ability to allow both it and a conventional compliant pin connector to be mounted on a single printed circuit board. For instance, user specifications may demand that electrical connectors be positioned on both sides of a double-sided printed circuit board. Generally speaking, a first side of the board will contain conventional wave solderable compliant pin connectors, which are characterized by high assembly costs. In order to minimize additional assembly costs, the second side of the printed circuit board must receive a non-solderable type connector, the latter being characterized by relatively lower costs of installation.
  • the connector of the present invention given its separable contact principle between the connector and the printed circuit board, is ideally suited for the preceding application, as well as other applications wherein flexibility and economy is desired.
  • the electrical connector possesses numerous other electrical and mechanical benefits over conventional devices. Electrical features of the connector include improved rise times and lower drive capacitance as opposed to those for typical compliant pin connectors. Furthermore, RF radiation concerns attendant to compliant pin connectors are eliminated with the present invention.
  • the mechanical features of the electrical connector enable it to tolerate more pin insertion/withdrawal cycles than conventional compliant pin devices and, as previously discussed, liberate it from the specialized installation and maintenance protocols required for conventional electrical connectors.
  • the present invention provides a novel electrical connector which successfully integrates a dual-in-line contact principle, which performs wipe and contact functions between the socket contact and the inserted pin, and which utilizes a GTH separable contact principle between the connector and the associated printed circuit board.
  • the prior art also generally discloses various means and methods by which the socket contacts of a receptacle of an electrical connector are engaged on a printed circuit board utilizing a compliant pin principle.
  • U.S. Pat. No. 4,585,285 to Martens which was patented on Apr. 29, 1986, shows a multi-row press fit connector wherein a plurality of contacts reside in the connector body and extend therethrough, whereby a compliant end of the contacts may be press fit into a printed circuit board.
  • U.S. Pat. No. 3,685,001 which issued to Krafthefer on Aug. 1, 1972, discloses an electrical connector characterized by a receptacle wherein depending tail members of the contacts disposed therein are adapted to be passed through a printed circuit board and are soldered in place.
  • the prior art discloses a socket contact member which is capable of performing a wiping and a contact action.
  • the latter principle is broadly referred to in U.S. Pat. No. 4,062,610 of Dec. 13, 1977 to Doty et.al. As shown therein, two surfaces on the contact perform a wiping action when such surfaces come into contact with an inserted post.
  • the invention pertains to an electrical connector including a receptacle body which is provided with a plurality of passageways extending from the top wall of the body through the bottom wall of the body.
  • a dual-in-line contact member is disposed in each of the passageways.
  • Each of the contact members has a first convex portion and a second convex portion facing toward the interior of the passageway in a pin facing direction, as well as a depending contact leg portion which projects through the bottom wall of the passageway and extends in a pin opposing direction.
  • the receptacle is adapted to receive corresponding male pin contacts or posts of a plug member, such that a pin contact is inserted into each of the passageways of the receptacle.
  • the first and second convex portions of the contact members provide first and second contact points for the inserted pin, and perform wiping functions with respect to the pin.
  • the receptacle is adapted to be separably mounted in electrical communication on a printed circuit board by means of the contact legs contacting a conductive strip on the printed circuit board.
  • the contacts are adapted to be associated with through holes and/or solder pads provided on the printed circuit board.
  • the contacts utilize soft metals at high contact pressures so that, upon mating of the contacts, the metal is upset and the resultant joint prevents contamination gases from entering the contact area.
  • FIG. 1 is a front plan view of the connector of the present invention
  • FIG. 2 is a top plan view of the connector of the present invention.
  • FIG. 3 is a side cross-sectional view of the connector taken through line A--A of FIG. 2;
  • FIG. 4 is an enlarged fragmentary view of the socket contact of the connector as it appears when engaging a pin contact inserted into the connector;
  • FIG. 5 is a plan view of a typical board hole and solder pad configuration for a printed circuit board to be utilized with the electrical connector.
  • the electrical connector comprises a receptacle body, indicated generally at 10, fabricated as an integral molding of an insulative material, preferably a glass-filled polyester material.
  • the body is defined by a front wall 12, a rear wall 14, a pair of end walls 16, a top wall 18, and a bottom wall 20.
  • a plurality of spaced apertures or passageways 22 are provided in the body, extending in the body through the top wall, to and through the bottom wall of the body, as most clearly shown in FIG. 3.
  • the passageways are oriented in the body to form two parallel rows of spaced passageways.
  • the rows as further shown in FIG. 2, are staggered with respect to each other.
  • the two rows of passageways are separated by a central wall 24 of the receptacle body.
  • a projecting shoulder 26 is formed on each of the sides 28, 29, of the central wall so as to project into each of the passageways.
  • a contact member 30 is disposed in each of the passageways 22.
  • the contact members 30, which are of the dual-in-line type, are each formed from a blank of electrically conductive material.
  • Each of the contact members is defined by a generally flat shank portion 32, the first end of which terminates in a first convex portion 34, and the second end of which terminates in a bent depending leg 36.
  • First convex portion 34 is provided with a cut-out 38, through which projects the terminal end 40 of a second convex portion 42 which extends from the first end of the shank.
  • both the first and second convex portions are disposed on what may be called the pin facing side 43 of the contact.
  • FIG. 3 depicts the contact members 30 as they appear when disposed within the passageways provided in the receptacle body.
  • the pin facing side 43 and, hence, the convex portions 34 and 42 face the interior of the passageway
  • the pin opposing side 44 of the contact member faces and substantially abuts the interior surface 46 of the front or rear wall of the receptacle body.
  • Each of the contact members is retained in position within its respective passageway by means of a projection 48 provided on the contact member on its pin facing side engaging beneath the shoulder 26 on the central wall of the receptacle body.
  • the depending leg 36 of the contact member projects through the passageway at the bottom wall 20 of the receptacle body so as to extend toward the front or rear walls of the receptacle.
  • the electrical connector as so described is adapted to mate with a plug member (not shown) containing a plurality of male pin or post contacts to which a cable is electrically connected.
  • a typical male pin 50 of such a plug member is illustrated in FIG. 4, which depicts the pin contact as it appears in relation to the female contact member 30 when the pin is inserted into a passageway 22 of the receptacle.
  • the first and second convex portions of the female contact provide first and second contact points for the pin member, as well as first and second wiping action points for the male pin, thereby providing redundancy and ensuring a controlled wipe-contact sequence. Full insertion of the pin contact is achieved when the tip of the pin contact abuts the projection 48 on the contact member.
  • the receptacle in turn, is intended to be separably mounted on a printed circuit board by means of the legs 36 of the contact members contacting a conductive strip on the printed circuit board under a gas tight contact principle.
  • the legs 36 are provided with a non-gold plating, preferably comprising 200 micro inches of tin-lead, by means of which the legs 36 function as gas tight contacts and may be brought into electrical contact with the printed circuit board.
  • the soft metals are upset and the resulting joint prevents contamination gases from entering the contact area.
  • the receptacle is adapted to accommodate both standard plated through holes in a printed circuit board, as well as solder pads with no through holes.
  • FIG. 5 illustrates a board hole and solder pad configuration for the electrical connector, wherein it can be seen that the extended solder pads 51 provide the flexibility of accommodating the separable connector, as well a a conventional compliant pin connector. As previously discussed, however, the contact legs of the electrical connector of the invention are adapted to be associated with solder pads without any holes and without a pad extension.
  • the receptacle body is provided proximate the end walls 16 with a jack screw 52.
  • Each of the jack screws passes through the body, and is adapted to be inserted into a corresponding hole in the printed circuit board.
  • the present invention therefore, provides an electrical connector in the form of a receptacle containing a plurality of dual-in-line female contact members which are provided with two contact portions for electrically engaging a male pin contact and for performing a wiping function with respect to the pin, and having gas tight contact means for separably connecting the connector to a printed circuit board.
